Description
The present invention relates to a kind of device that granular raw materials for sintering is added sintering machine.More particularly, relating to a kind of raw material that conveyer is shipped adds sintering machine material bed, also can be controlled at the device that the material bed is gone up the distribution of raw material granularity on the bed depth direction of piling up.
In common sintering machine, raw materials for sintering always is to be stored in a kind of buffering hopper, is stopped by the roll-type dispenser that is positioned at below this hopper, and imports by a deflector in a kind of sintering dolly of operation at a predetermined velocity.Move with dolly after making raw material in dolly, be stacked into predetermined altitude by deflector.Again by an ignition furnace from it portion light carbonaceous material in the raw material, and make the bed of material begin from top to carry out sintering to the bottom by the air draft pipe and the connected air exhauster that are contained in below the dolly.
Yet, the new method of a kind of sintering granular feedstock of now having greatly developed is that to make the raw materials for sintering nodularization of powdery become granularity earlier be the granular feedstock of 8mm, add in the sintering machine then, consequently improved the gas permeability of sintering bed, the reproducibility and the output of sintered products, and made the sintering of material more effective.But, adopt this method, taken great efforts make granular material may the buffering hopper in or in the roll-type dispenser dams process, be pulverized.And, installing to the material grain that granularity is bigger in the raw material in the dolly rolls in dolly easily, then difficult rolling of material grain that granularity is less, therefore, the size distribution of upper and lower that is deposited in the bed of material in the dolly is just different, under the bigger situation of size distribution difference, the upper and lower raw material just can not carry out sintering equably, the phenomenon of sintered products quality inequality therefore will occur.
The objective of the invention is to overcome the above-mentioned difficulties that in the prior-art devices raw materials for sintering is added sintering machine, and provide a kind of raw materials for sintering is added the feeding device of sintering machine, adopt this device.Raw materials for sintering can not pulverized, and can control the size distribution of upper and lower part raw material on the sintering dolly.
In order to achieve the above object, the invention provides and a kind of raw materials for sintering is added the feeding device of sintering machine, this device comprises:
Article one, transport the reciprocating conveyor of granular raw materials for sintering:
Article one, reception is packed into by the wide formula conveyer in the sintering dolly of predetermined direction motion from the granular feedstock of above-mentioned reciprocating conveyor and with this raw material:
Reception imports deflector in dolly from the above-mentioned granular feedstock of above-mentioned wide formula conveyer and with it:
A support plate that blocks the raw material in the dolly of packing into from behind, this support plate are positioned at the below of the opposite of above-mentioned deflector, wide formula conveyer and the top of dolly.
By below in conjunction with being described in detail an of accompanying drawing, will more understand above-mentioned purpose of the present invention and other purpose and advantage of the present invention.
Accompanying drawing is the vertical cross section that shows most preferred embodiment of the present invention.
Following mask body is described in detail an example of the present invention with reference to the accompanying drawings.Accompanying drawing is a kind of vertical cross section that raw materials for sintering is added the device of sintering machine.A reciprocating conveyor 12 that is used for transporting raw materials for sintering 11 is wherein arranged.One group wide formula conveyer 13 is arranged below this conveyer 12.Dispose sintering dolly 14 and deflector 15 below wide formula conveyer 13, the dolly 14 that stows raw materials for sintering 11 moves along direction shown in the arrow A in the accompanying drawing, makes raw materials for sintering 11 be accumulated to predetermined bed depth by deflector 15.Raw material 11 back of piling up in above-mentioned dolly 14 have one to be used for controlling the device 20 that raw materials for sintering is piled up situation, and it is made up of a support plate 16, several poles 17 and a driving governor 18.Support plate 16 is used for blocking from behind the raw material 11 that is deposited in the dolly 14, pole 17 is used for supporting above-mentioned support plate 16,18 difference of driving governor drive upper rack posts and the lower fulcrum bar gradient with control support plate 16 in the opposite direction, and it also can promote the direction that support plate 16 moves with respect to raw material (in the accompanying drawing shown in the arrow A) and move forward or backward.Support plate 16 also can promote it by driving wheel by the above-mentioned driving governor 18 on the track that is installed in the appropriate location forward or backward, and support plate 16 also can make it do upper and lower moving by controller 18.Be provided with several monitoring sensors 21, be used for monitoring near support plate 16 states of piling up raw material 11.Each monitoring sensor 21 comprises a television eye and the supersonic sounding device by a control room (not shown) remote control.Introduce the working condition of the raw materials for sintering feeding device that constitutes in a manner described below.Raw materials for sintering 11 is sent on the reciprocating conveyor 12 after granulator (for not shown for the purpose of the simplified illustration) comes out; one end of conveyer 12 is reciprocating along its belt direction, with raw materials for sintering 11 along the width of wide formula conveyer 13 be added to equably be positioned at its downside and with the perpendicular wide formula conveyer 13 of its direction of motion on.The raw material 11 that arrives sintering dolly 14 top certain positions by one group wide formula conveyer 13 is added in the dolly 14 equably along the width of the dolly 14 between deflector 15 and the support plate 16; because the granular feedstock made from above-mentioned granulator 11 is not stored in the buffering hopper; also can't help the roll-type dispenser stops, so the quantity of pulverized particulate material significantly reduces.
After the raw material 11 of dolly 14 of packing into is accumulated to predetermined height by deflector 15 guiding, press in the accompanying drawing direction shown in the arrow A with dolly 14 and move.After this, the carbonaceous material that contains in the raw material 11 is just lighted from above by an ignition furnace.As the example of prior-art devices, the sintering of raw material 11 is to carry out from top to bottom by means of being installed in dolly 14 following air draft pipe and the beginnings above the bed of material of connected air exhauster.
The raw materials for sintering of piling up 11 is by being positioned at deflector 15 opposites and the support plate 16 in raw material 11 back blocks.Granular raw materials for sintering leniently formula conveyer 13 is fallen on the surface of piling up raw material.Block by above-mentioned support plate 16 owing to pile up raw material 11, so they only roll across a bit of distance (representing with L among the figure).The gradient of this segment distance that granular feedstock rolls down is less, and therefore granule is deposited in the difference that the bed of material upper and lower part size distribution of piling up in the dolly is caused on bed of material top owing to bulky grain tumbles the bottom of the bed of material easily with regard to having reduced.Correspondingly, the inhomogeneity of the sintered products that causes because of the difference of size distribution has also reduced.
In some cases, according to the needs of mixed method or sintered products manufacture method, wish to have slight size distribution difference.For example, the surface that adheres to raw materials for sintering with fine coal and coke powder (dusty fuel) as sintering fuel just wishes that there is more dusty fuel on the bed of material top in the sintering dolly 14 than the bottom when improving the quality of sintered article.Because the air of burning usefulness is to be flowed to the bottom by the top of the bed of material, and raw material is the top from the bed of material, sintering from top to bottom, therefore, it is long that the raw materials for sintering of material layer lower part is in the raw material on time ratio bed of material top of high temperature, so required dusty fuel is just less.
By promoting the gradient that pole 17 is regulated the support plate 16 of bed of material control device 20, perhaps adopt driving governor 18 to move forward and backward or move up and down the position of support plate 16, all can control the distribution situation of bed of material upper and lower part dusty fuel.According to the character of raw materials for sintering, also can not only regulate the gradient of support plate 16 but also regulate its position, also can regulate wherein one separately.In other words, the powder raw material in the bed of material is in the distribution situation of upper and lower part, mainly is that the distance L that rolls down according to raw material and the gradient of distance L are controlled.The gradient of adjusting support plate 16 can change the distance (representing with M in the accompanying drawing) between dolly 14 and support plate 16 ends, can control the difference that support plate 16 following raw material granularities distribute thus, like this, just can support plate 16 be moved forward and backward or change the difference that gradient reduces to be deposited in the raw material upper and lower part size distribution in the dolly by driving governor 18, thus the stable sintered products of obtained performance.
The supervising device 21 that is used for monitoring and survey raw material rolling distance L and support plate 16 gradients be installed in the reinforced position of raw materials for sintering near.An available TV camera or sonac are as the sensor of supervising device.TV camera is in order to observing the accumulation situation of raw materials for sintering intuitively, and sonac then is used for measuring quantitatively the height of the bed of material.
